Special process features of high-density technical ceramic Preparation of the semiproduct for sintering

The influence of the degree of aggregation of powders, properties of aggregates (size, strength, porosity) on the degree of sintering and characteristics of the microstructure of the manufactured ceramics is shown. The conditions for obtaining powders with a low degree of aggregation, as well as methods of powder disaggregation, are considered. Requirements for powders that provide the same pore size in compacts and a uniform degree of sintering throughout the volume of products are formulated. Tab. 2, ill. 2, bibliography: 9 titles.
